EPM3128ATI144-7N 개요
What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic IC that sits between simple PLDs and FPGAs in the programmable logic hierarchy. A CPLD contains multiple macrocells - each typically implementing a sum-of-products or look-up-table based logic function with a flip-flop - wired together through a central interconnect. Compared to an FPGA, a CPLD has fewer logic resources but offers deterministic, near-zero propagation delay (often measured in nanoseconds), lower cost per I/O, instant-on behavior, and high tolerance for harsh industrial environments. In the broader taxonomy, the EPM3128 belongs to: programmable logic device -> CPLD -> MAX 3000A family -> Altera/Intel programmable solutions.
Key features include 7.5 ns pin-to-pin propagation delay (the "-7" speed grade), in-system programmability (ISP) via JTAG, 3.3V core VCCINT with 3.3V or mixed 2.5V/1.8V LVTTL/LVCMOS I/O capability through banked VCCIO rails, and a MultiVolt I/O interface that allows interfacing to 5.0V, 3.3V, 2.5V and 1.8V devices. Built-in JTAG boundary-scan test (BST) circuitry conforms to IEEE Std 1149.1, supporting both manufacturing test and in-field reprogramming. Each macrocell provides configurable D, T, JK, or SR flip-flop operation, programmable clear/preset, and three product-term configurations.
Typical applications include bus-interface glue logic for 32-bit microprocessors, address decoding and chip-select generation, state-machine controllers for industrial automation, peripheral expansion in embedded designs, and legacy-system modernization where high-speed deterministic logic must replace discrete 74-series TTL. The 144-pin TQFP package provides 96 user I/O and a 0.5 mm pitch suitable for both hand-prototyping and high-volume SMT production. Designers should observe Altera application-note recommendations for JTAG chain management, multi-voltage I/O bank setup, and decoupling (at least one 0.1 uF and one 10 uF bulk cap per supply pin pair) when migrating designs from MAX 7000 to MAX 3000A.

일반적인 애플리케이션
EPM3128ATI144-7N 적합 용도: 6 애플리케이션s: Microprocessor Bus Glue Logic, Industrial Automation State-Machine Controllers, Legacy System Modernization, Peripheral Expansion & Chip-Select Generation, Communications Infrastructure Glue Logic, Test & Measurement Front-End Logic.
Microprocessor Bus Glue Logic
The EPM3128ATI144-7N's 128 macrocells and 96 user I/O make it a strong fit for microprocessor bus-interface glue logic. Typical use is to implement address decoders, chip-select generation, wait-state insertion and bus-width translation between an MCU/CPU and external peripherals. The 7.5 ns tPD keeps decoded signals within one clock cycle at 133 MHz bus speeds, while the JTAG ISP interface lets firmware engineers iterate decoder maps without reworking the board. Compared to discrete 74-series TTL, the EPM3128ATI144-7N consolidates dozens of packages onto a single 144-pin TQFP, reducing PCB area and BOM count.

Industrial Automation State-Machine Controllers
For industrial automation, the EPM3128ATI144-7N serves as a deterministic state-machine controller for conveyor logic, machine-tool interlocks and PLC expansion I/O. The -40C to +85C industrial temperature range and CMOS EEPROM non-volatile configuration make it tolerant of factory-floor temperature swings and brown-out events. With 129.9 MHz fMAX and 7.5 ns tPD, multi-state feedback loops stay within microsecond deadlines even with many registered outputs. The 96 user I/O directly drive opto-isolated inputs and 24 V relay/solenoid outputs through external drivers, removing the latency variability of software PLC loops.
추천
Legacy System Modernization
Engineers modernizing 1990s/2000s designs built around discrete 74LS/74F logic can drop the EPM3128ATI144-7N into existing footprints to replace dozens of DIP/SOIC packages with a single TQFP. The 144-pin TQFP package exposes enough user I/O to re-host dense address-latch, FIFO-flag and interrupt-priority-encoder networks. Designers can re-implement the legacy logic using the original Quartus II project (or a modern Quartus Prime version) without modifying the host PCB. Instant-on CMOS EEPROM configuration preserves the deterministic behavior that the legacy discrete logic provided.
추천
Peripheral Expansion & Chip-Select Generation
In embedded designs, the EPM3128ATI144-7N is commonly used as a peripheral expansion device, generating chip-select and address-mux signals for SRAM, NOR flash, FPGA configuration memories, and bus peripherals. Its 128 macrocells can decode up to 64 million unique address ranges with multiple product-term AND-OR planes. The 7.5 ns tPD ensures chip-select signals arrive in the same clock cycle as the bus address, eliminating wait states in tightly coupled memory subsystems. JTAG ISP lets board designers update chip-select maps during bring-up without swapping parts.

Communications Infrastructure Glue Logic
The EPM3128ATI144-7N is widely used in telecom and networking line cards for protocol-bridging glue logic between PHYs, switches and FPGAs. Implementations include MDIO bus multiplexing, I2C/SPI/GPIO expansion, LED-status drivers, and backplane-reset sequencing. The 129.9 MHz fMAX and 96 user I/O accommodate multiple bus standards on a single device. The MultiVolt I/O interface connects directly to 1.8V, 2.5V and 3.3V PHYs without external level shifters, simplifying mixed-voltage designs common in modern line cards.
추천
Test & Measurement Front-End Logic
Test and measurement instruments use the EPM3128ATI144-7N to implement trigger logic, channel-multiplexer control, range-switching relays, and front-panel LED/display scanning. The deterministic 7.5 ns tPD preserves timing integrity in trigger paths where software jitter would distort measurements. With 96 user I/O, a T&M front-end can drive relay arrays, analog muxes and display drivers from one device. Non-volatile EEPROM configuration survives instrument power cycles, retaining calibration-channel mapping without an external boot PROM.

설계 노트
Estimated: at typical 100 MHz operation across 96 user I/O with average 5 mA per switching output, total VCCIO current is approximately 0.48 A; VCCINT current is typically 30-60 mA depending on toggle rate. Provide at least one 0.1 uF X7R ceramic bypass capacitor adjacent to every VCCINT/VCCIO pin pair, and one 10 uF bulk tantalum or ceramic cap per supply rail close to the package. Inadequate decoupling on the 144-pin TQFP is a common cause of JTAG programming failures.
The 144-pin TQFP package has 0.5 mm terminal pitch; use 0.20 mm-wide PCB traces and 0.30 mm clearances to maintain manufacturability. Place all four JTAG pins (TCK, TMS, TDI, TDO) on a dedicated 4-pin header or test pad array to allow in-system programming without removing the board. Tie TMS and TDI high through 10 kohm pull-ups at power-up to place the JTAG TAP controller in a known state. The GCLK and OE pins should also be pulled to defined logic levels through 10 kohm resistors if left unused.
The MAX 3000A I/O structure is fast-edge CMOS; long PCB traces (>50 mm) should be terminated to avoid reflections on clock and one-shot signals. When interfacing to 5 V logic, the MultiVolt interface tolerates 5 V inputs on VCCIO=3.3 V outputs, but bidirectional buses still require external 5 V-to-3.3 V level shifters. Use the OE/GCLR global networks for asynchronous clear or output enable rather than product-term-routed signals to guarantee glitch-free operation.
Do not confuse the 'N' suffix (lead-free/RoHS-compliant finish) with temperature grade. The 'I' in EPM3128ATI144 indicates industrial (-40C to +85C); 'C' would indicate commercial (0C to +70C). Using a 'C' grade in an outdoor industrial enclosure will cause field failures. When migrating designs between MAX 7000 and MAX 3000A, recompile with Quartus II 13.0 or earlier; later Quartus Prime releases dropped MAX 3000A support and the project will not assemble.
